Welcome to Laser Laboratory

The Laser Laboratory belongs to  the division of Electronics and Computing of the Physics

An overview of the fs upconversion and TPEF experiments (2)

Department  at the University of Patras, Greece. It is located on the second floor of building A of the Physics Department. It was established in 1974.

Its history can be divided in two periods. In the first period (1974-1997) the main research area was gas lasers while in the second period (1998-todate) the research is focused on ultrafast spectroscopy, nonlinear optics, photonic materials and fiber optics. The laboratory provides to young students the ability to understand the physics of lasers and applications both theoretically and experimentally. Furthermore, high quality scientific research is realized through its modern equipment.
